Does new TC8305C replace both Arris and RCA modem?

New Poster

Does new TC8305C replace both Arris and RCA modem?

I currently have an Arris device that was installed in my basement which has a cable connection and a telephone connection that is connected directly to the phone companies external/outside box. In my office on our main floor I have an RCA modem that is connected to my current netgear wireless access point. 

 

Does the new TC8305C device replace both the Arris device in my basement and the RCA modem in my office? Do I connect the TC8305C telephone connection to a telephone wall jack in my home in order for my telephones to work?

The TC8305C is a "gateway" device; it supports telephone/internet and has wireless capabilities. You can just get a straight modem and replace your RCA if you like tho. Then it's just a matter of swapping your modem. 

 

If you want to replace your three devices with the TC8305C then that's okay too. Just install it where your RCA modem is currently located. Plugging in the phone line from the TC8305C to the phone wall jack will energize the entire phone system in your house, provided that phone jack currently works with your Comcast voice service.
